SPECIFICATION forming part of Letters Patent No. 620,865, dated March. 7, 1899.

Application filed .Ttm18, 1895.

To all whom it may concern.-

Be it known that I, HENRY LoUIs DEs AN- the path of the current and tolower the electrical resistance from rail to rail,- which is by my method made so low as to render it possible to avoid using nl e-tals, such ascopper, of high conductivity and thus to diminish the cost. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the rails at a joint, showing one form of my rail-bond. Fig. 2 is an end elevation of arail containing the form of rail-bond shown in Fig. 1, with bond and fish-plates shown in section. At Fig. 3 is shown another form of rail with the same bond. Fig. e is a plan of that which is shown in Fig. 1..

a. a are portions of two abutting rails in a track joiined together by the fish-plates b b.

Serial No. 553,226. (Ndiiiodehl nection with the rails a a, and the current will pass freely between these rails.

The form of rail-bond shown in Figs. 1, 2, and 3 has the advantage that every passage of car-wheels over the rails will tend to press the bond downward and compress the metal, so as to fill any crevices which might form between it and the rail.

Having nowfully described my invention, what I claim as new, and desire to secure by LettersPatent, is'- In a railway, the combination of rails, having grooves in the tops of the treads thereof, and a bond, for electrically connecting the rails, fitting tightly within said grooves.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
